On numerical semigroup elements and the $ℓ_{0}$ - and $ℓ_{\infty}$ -norms of their factorizations

Sogol Cyrusian, Alex Domat, Christopher O'Neill +3

A numerical semigroup $S$ is a cofinite, additively-closed subset of $Z_{\geq 0}$ that contains 0, and a factorization of $x \in S$ is a $k$ -tuple $z = (z_{1}, \dots, z_{k})$ w…

Betti elements and full atomic support in rings and monoids

Scott T. Chapman, Pedro García-Sánchez, Christopher O'Neill +1

Several papers in the recent literature have studied factorization properties of affine monoids using the monoid's Betti elements. In this paper, we extend this study to more gener…
